MACHINE FOR ROLLING METAL FORMS.

SPECIFICATION forming part of Letters Patent No, 694,722, dated March 4, 1902.

Application filed Jlmfi 16, 1899. Serial No. 720,869. (No modal.)

To all whom it may concern:

Be' it known that I, CHARLES FREDERICK BROOKER, a citizen of the United States, residing at Ansonia, State of Connecticut, have invented a Machine for Rolling Metal Forms, of which the following is'a specification.

My invention relates to a machine constructed to rollcopper forms; and it consists of a special arrangement of edging-rolls, facingrolls, guides, clutches, and other operating mechanism by means of which a strip of copper or other metal may be firststraightened and subsequently rolled to a variety of shapes and finally delivered from the machine in a finished state.

The object of my invention is a machine by which bodies of copper may be given definite I shapes by rolling instead of drawing, as has heretofore been the practice, and thereby, materially decrease the cost of production of such shapes.

In the drawings similar numerals indicate like parts in the several figures.

Figure 1 is a front view of the machine with the small directing-rolls shown in Fig. 2 removed. Fig. 2 is an end view and vertical section through the supporting-bracket and one of the adj usting-screwsfor the housings which carry the edgingmollsand also shows the main frame for thefacingrolls broken away at the bottom in order to illustrate the position of the adj usting-screws for the lower of the facing-rolls. Fig. 3 is a front View of the facing-rolls with their supporting-frame, with one side of the supporting-frame and also the universalbearings and driving'shafts shown in vertical section. Fig. 4 is a side view of the guides in front and behind the.

facing-rolls, with the facing-rolls in vertical section. Fig. 5 is a front view of the guide located between the edging-rolls and the facing-rolls.

In the drawings, 5 indicates the supportingframe for the facing-rolls. The frame contion of the axes altered at will.

bearings 10 are supported on and made adv17 of the facing-rolls 18. In the drawings,

Figscl and 3, the facing-rolls are shown as angular-1y disposed as regards each other 2'. 6., in the position which they would be arranged to roll a V-shaped copper form. By means of the adj usting'screws 13 and 14 the facing-rolls may have their axes adjusted as regards each other-that is, the axes of the rolls may be parallel or the angular inclina- It will be observed that by reason of the adj usting-sorews l3 and 14: both of the rolls may be adjusted and not one roll, as is usually the case. The ends 19 of the rolls 18 are hexagonal in shape and connected through eouplings20, also hexagonal on their interior, to the hexagonal driving-shaft 21. Theparticular shape given to these parts is not material. I V

' Located on the outer sides of the uprights 7 are the thrust-plates 22, which serve to prevent the lateral displacement of the verticallyadjustable bearing-seats 15, but do not interfere with the rolling of the piano-convex bearings 16.

Located on the front of the machine and in front of the facing-rolls and formed as a part of the machine by casting or connected there to in any suitable manner, as by means of bolts, is a bracket-support 23. The top of this support is cut away to form a dovetailed longitudinal slot 24 and concave longitudinal opening 25.

Located on the top of the bracket-support motion to and from each other along the top of the bracket-support 23. The upper portion of the housings 26 are formed as bearings 30, and located and. supported in these hearings is a slotted shaft 31. Located upon this shaft are the beveled gears 32. These gears are loose upon the shaft, and therefore capable of longitudinal motion on the shaft, and receive motion from the shaft through the instrumentality of keys 33. The gears 32 mesh with the gears 34, which are carried in the bearings 35. Connected to the gears 34 are the short hexagonal shafts 36.

Mounted on the shafts 37, which have their bearings in the bottom of the housings, are the edging-rolls 38. These rolls may be given any surface contour desired. Those shown in the drawings have two diameters, the greater diameter being at the bottom.

Mounted on the shafts 36 are the slotted clutches 39, having hexagonal openings which correspond to the shape of the shafts 36 and 37. Vertical movement is imparted to these clutches by means of the levers 40, which are pivoted at 41 to the housings 26. The inner ends of the clutch-levers are forked, as at 42, and partially surround the clutches, to which each is loosely connected through pins 43, which take in the slots 44 of the clutches 39. By means of the levers 40 the edging'rolls 38 can be thrown into and out of operation, as desired.

My object in providing the edging-rolls with independent clutches is for the purpose of permitting the edging-rolls to be operated separately or conjointly. By operating the rolls separately-that is, allowing one roll to run loose and the other to be driven positively-the strip passing the machine may be straightened before it is carried between the facing-rolls. Further, by mounting the edging-rolls on independent shafts separate from the driving-shafts I am able to readily substitute edging-rolls of different surface contour.

45, 46, and 47 represent gears intermediate of the main driving-shaft and the shaft 31.

The arrangement of these gears is such that the speed of the edging and facing rolls will be the same.

Mounted between the edging-rolls and the facing-rolls is the front guide 50, and located behind the facing-rolls is the back guide 51. These guides consist of pairs of oppositely disposed guide-boxes 52. The shape given to these boxes is best shown in Fig. 5-that is,

The guide-boxes 52 are mounted upon the horizontal plate 53, which is supported-by the vertical side frames 54, secured to the uprights 7 of the machine. The guide-boxes 52 are longitudinall adjustable upon the supporting-plate 53 and to or from the facingrolls 18 by means of the screws 55, and they are also adjustable relatively to each other 5. 6., transversely of the plate 53 by means of the screws 56-so that the distance between them may be altered.

The guide-boxes 52 of the guide 50 project between the rolls 18, but are not carried past the vertical axis of the rolls, whereas the guide-boxes of the guide 51 project past the vertical axis. This is the only difference of construction between the guides 50 and 51, and this difference in construction is for the purpose of preventing a strip when passing the rolls from following the curvature of the rolls and turning upward. The shape of the guide-boxes projecting through the rolls prevents this.

Located in front of the edging-rolls 38 and supported upon the bracket 23 is a pair of vertically-disposed directing-rolls 57 and back of them a pair of horizontally-disposed adjustshape is introduced through the directingrolls 57 and 58 until it is caught between the oppositelydisposed edgingrolls 38. These rolls determine the width and shape of the edges of the strip. After leaving the edgingrolls it passes into the guide 50 and thence through the facing-rolls, which determine the general cross-section of the strip, and thence through the rear guide 51 and out of the machine. It will be observed that the path of movement of the strip through the machine from the time it enters the directing-rolls 57 until it leaves the machine is along astraight horizontal plane. The result of the action of the machine upon the'strip is a copper body of definite and predetermined shape, straight and with finished edges. As has been explained, the contour of the body may be changed by altering the relation of the axes of the facing-rolls and the contour of the edging-rolls, and bodies of different width may also be obtained by changing the distance between the pairs of facing-rolls and pairs of edging-rolls or of the one relatively to the other.
